The observed flux at time t reads F(t)
= FSA(t) + FB, where
the source flux FS and the background flux
FB are specific to each observing site and filter,
while A(t) denotes the theoretical magnification.
In order to put
different data sets
(ti, Fi, σFi) on the same plot, we show the theoretical magnitude shift
Δm = 2.5 lg A(t) along with
mi = 2.5 lg Ai and the error bar
σmi = [2.5/ln(10)] [σFi/|FSAi|]. Epochs for
which Ai ≤ 0 are marked by small stars below the
abscissa.

All data are the result of preliminary reductions. Despite the fact that
all teams aim at providing as accurate data as possible,
